I have a Kala super tenor (19" neck) and I like re-entrant high g tuning (gCEA). I find the re-entrant D tuning, often used for baritones, a bit too low sounding because I prefer a "ukulele" kind of tone. I sent an e-mail to Kala and they said that for high g tuning I can use ANY tenor strings...even if the super tenor 's neck is two inches longer. So I did it: I tried first with regular D'Addario tenor fluorocarbons, and I found that the tension was a bit too high...now, Kala says do not worry, but to me the higher tension was making the tone too bright. Then, I tried with regular D'Addario tenor nylon strings, because nylon strings have a lower tension. It worked well, the super tenor tuned gCEA with nylon sounded good, and sounded like an ukulele (which is what I like). But I am not a big fan of nylons....Currently, I am set on this solution: I use TENOR cGEA strings on my super tenor (any brand, including fluorocarbons, Aquilas etc...) but I tune the ukulele down one full step, i.e. f Bb D G. I love how it sounds, the tension is perfect (not too high, not to sloppy) and the sound is beautiful, with lot of sustain. And....if I want to play in cGEA, I just put a capo on the second fret ! I am liking this solution so much that I set my baritone the same way (i.e. using tenor strings and tuning it to f Bb D E). In fact, the main reason why I like super tenors and baritones is because I am 6ft tall and have big hands, and love the extra room of super tenors and baritone necks. But I love the re-entrant tuning because I want a "ukulele" sound. So my suggestion to you is: for high g tuning, use tenor nylon strings. Or, use any other kind of strings and tune down to f Bb D G. Try it !
